Just yesterday I read the thinkwiki, which tells me:

”Battery health

Batteries, especially of the modern Li-Ion type, wear out quicker when 
they hold a large charge or are subject to higher temperatures (see above).

If you use your laptop at a desk, reduce battery wear by maintaining an 
appropriate charge level. When possible, remove Li-ion batteries while 
operating from AC as the notebook gets hot enough inside for that to 
damage the battery in the long run, even if charging is stopped.“

So I mostly run my X61s without battery and never got any problems.
